Hi. I am a newly qualified TEFL teacher about to start teaching one to one to a very basic Spanish adult who wishes to learn english for an interview. I would like any ideas please that you think may help me

I suggest you get a good course book such as English File and work your way through that. You can start the first lesson with numbers and basic questions such as what's your name and where are you from. That'll give you a better idea of level and pointers for the second lesson. Remember to focus on pronunciation and listening. These will be important in an interview.

Do you have any idea about what type of interview he needs to learn English for? Is it a job interview? What kind of job is it? I really have no idea what it means to want to learn English for an interview, but if you know the answers to the questions above, you could then have an idea about what type of vocabulary and expressions to teach.On the other hand, as you say that your student is a beginner, here are some free lesson plans with a variety of activities for beginners that could help.Good luck!http://teachers.onlineenglishexpert.com/category/english-lesson-plans/a1-lesson-plans/
